====== Signature Types ======

The sample codes for creating different types of signatures stated in the standarts are listed below. See the section [[en:esya:eimza:tipler|Signature Types]] for the information about signature types

The sample codes are in the package ''tr.gov.tubitak.uekae.esya.api.xades.example.formats''.

===== BES Signature =====

''BES'' signature creation is as follows:

<sxh java>
// create context with working directory
Context context = createContext();

// create signature according to context,
// with default type (XADES_BES)
XMLSignature signature = new XMLSignature(context);

// add document as reference, but do not embed it
// into the signature (embed=false)
signature.addDocument("./sample.txt", "text/plain", false);

signature.getSignedInfo().setSignatureMethod(SignatureMethod.RSA_SHA256);

// false-true gets non-qualified certificates while true-false gets qualified ones
X509Certificate cert = JSmartCardManager.getInstance().getSignatureCertificate(true, false);

// add certificate to show who signed the document
signature.addKeyInfo(new ECertificate(cert.getEncoded()));

// now sign it by using smart card
signature.sign(JSmartCardManager.getInstance().getSigner(PIN, cert));

signature.write(new FileOutputStream(BASE_DIR + SIGNATURE_FILENAME));
</sxh>

===== T Signature =====

''T'' signature creation is as follows:

<sxh java>
// create context with working directory
Context context = createContext();

// create signature according to context,
// with default type (XADES_BES)
XMLSignature signature = new XMLSignature(context);

// add document as reference, but do not embed it
// into the signature (embed=false)
signature.addDocument("./sample.txt", "text/plain", false);

signature.getSignedInfo().setSignatureMethod(SignatureMethod.RSA_SHA256);

// false-true gets non-qualified certificates while true-false gets qualified ones
X509Certificate cert = JSmartCardManager.getInstance().getSignatureCertificate(true, false);

// add certificate to show who signed the document
signature.addKeyInfo(new ECertificate(cert.getEncoded()));

// now sign it by using smart card
signature.sign(JSmartCardManager.getInstance().getSigner(PIN, cert));

// upgrade to T
signature.upgrade(SignatureType.ES_T);

signature.write(new FileOutputStream(BASE_DIR + SIGNATURE_FILENAME));
</sxh>

===== C Signature =====

''C'' signature creation is as follows:

The difference is the upgrade line, which is ''ES_C'' in this case.

<sxh java>
// upgrade to C
signature.upgrade(SignatureType.ES_C);
</sxh>

===== X-Type1 Signature =====

''X1'' signature creation is as follows:

The difference is the upgrade line, which is ''ES_X_Type1'' in this case.

<sxh java>
// upgrade to X1
signature.upgrade(SignatureType.ES_X_Type1);
</sxh>

===== X-Type2 Signature =====

''X2'' signature creation is as follows.

The difference is the upgrade line, which is ''ES_X_Type2'' in this case.

<sxh java>
// upgrade to X2
signature.upgrade(SignatureType.ES_X_Type2);
</sxh>

===== X-Long Signature =====

''XL'' signature creation is as follows:

The difference is the upgrade line, which is ''ES_XL'' in this case.

<sxh java>
// upgrade to XL
signature.upgrade(SignatureType.ES_XL);
</sxh>

===== Archival Signature =====

''A'' signature creation is as follows:

The difference is the upgrade line, which is ''ES_A'' in this case.

<sxh java>
// upgrade to A
signature.upgrade(SignatureType.ES_A);
</sxh>
